Knative 事件的传输加密

标志名称： transport-encryption

阶段：Beta，默认禁用

跟踪问题： #5957

概述

默认情况下，集群内的事件传输是未加密的。这限制了可以传输的事件类型，只能传输合规性要求较低（或合规性策略宽松）的事件，或者迫使管理员使用服务网格或加密 CNI 来加密流量，这给 Knative 事件的采用者带来了许多挑战。

Knative Broker 和 Channel 提供 HTTPS 端点来接收事件。鉴于这些端点通常没有公共 DNS 名称（例如 svc.cluster.local 或类似的名称），它们需要由非公共 CA（集群或组织特定的 CA）签名。

事件生产者能够连接到带有集群内部 CA 证书的 HTTPS 端点。

先决条件

安装

设置 SelfSigned ClusterIssuer

注意

ClusterIssuer 是 Kubernetes 资源，代表能够通过响应证书签名请求来生成签名证书的证书颁发机构 (CA)。所有 cert-manager 证书都需要一个处于就绪状态的引用颁发者来尝试响应请求。参考：cert-manager.io/docs/concepts/issuer/

重要

为了简化本指南，我们将使用 SelfSigned 颁发者作为根证书，但请注意此方法所带来的影响和限制，如 cert-manager.io/docs/configuration/selfsigned/ 中所述。如果您运行的是公司专用的私钥基础设施 (PKI)，我们建议使用 CA 颁发者。有关更多详细信息，请参阅 cert-manager 文档：cert-manager.io/docs/configuration/ca/，但您也可以使用任何其他可用于集群内部服务的颁发者。

  1. 创建 SelfSigned ClusterIssuer
    apiVersion: cert-manager.io/v1
kind: ClusterIssuer
metadata:
  name: knative-eventing-selfsigned-issuer
spec:
  selfSigned: {}
  2. 应用 ClusterIssuer 资源
    $ kubectl apply -f <filename>
  3. 使用先前创建的 SelfSigned ClusterIssuer 创建根证书
    apiVersion: cert-manager.io/v1
kind: Certificate
metadata:
  name: knative-eventing-selfsigned-ca
  namespace: cert-manager # the cert-manager operator namespace
spec:
   # Secret name later used for the ClusterIssuer for Eventing
  secretName: knative-eventing-ca

  isCA: true
  commonName: selfsigned-ca
  privateKey:
    algorithm: ECDSA
    size: 256

  issuerRef:
    name: knative-eventing-selfsigned-issuer
    kind: ClusterIssuer
    group: cert-manager.io
  4. 应用 Certificate 资源
    $ kubectl apply -f <filename>

为事件设置 ClusterIssuer

  1. 为事件创建 knative-eventing-ca-issuer ClusterIssuer

    # This is the issuer that every Eventing component use to issue their server's certs.
apiVersion: cert-manager.io/v1
kind: ClusterIssuer
metadata:
  name: knative-eventing-ca-issuer
spec:
  ca:
    # Secret name in the Cert-Manager Operator namespace (cert-manager by default) containing
    # the certificate that can then be used by Knative Eventing components for new certificates.
    secretName: knative-eventing-ca
    !!! important ClusterIssuer 的名称必须是 knative-eventing-ca-issuer。

  2. 应用 ClusterIssuer 资源

    $ kubectl apply -f <filename>

为事件组件安装证书

事件组件使用 cert-manager 颁发者和证书来提供 TLS 证书，在发布资产中，我们发布了可以根据需要自定义的事件服务器证书。

  1. 安装证书，运行以下命令
    kubectl apply -f https://github.com/knative/eventing/releases/download/knative-v1.21.0/eventing-tls-networking.yaml
  2. [可选] 如果您正在使用 Eventing Kafka 组件，请通过运行以下命令安装 Kafka 组件的证书
    kubectl apply -f https://github.com/knative-extensions/eventing-kafka-broker/releases/download/knative-v1.21.0/eventing-kafka-tls-networking.yaml
  3. 验证颁发者和证书是否就绪
    kubectl get certificates.cert-manager.io -n knative-eventing
    示例输出
    NAME                           READY   SECRET                         AGE
imc-dispatcher-server-tls      True    imc-dispatcher-server-tls      14s
mt-broker-filter-server-tls    True    mt-broker-filter-server-tls    14s
mt-broker-ingress-server-tls   True    mt-broker-ingress-server-tls   14s
selfsigned-ca                  True    eventing-ca                    14s
...

传输加密配置

transport-encryption 功能标志是一个枚举配置，用于配置 Addressables（Broker、Channel、Sink）应如何接受事件。

transport-encryption 的可能值为

  • disabled（这等同于当前行为）
    • Addressables 可以接受 HTTPS 端点的事件
    • 生产者可以发送事件到 HTTPS 端点
  • permissive
    • Addressables 应接受 HTTP 和 HTTPS 端点的事件
    • Addressables 应宣传 HTTP 和 HTTPS 端点
    • 生产者应优先将事件发送到 HTTPS 端点（如果可用）
  • strict
    • Addressables 必须不接受非 HTTPS 端点的事件
    • Addressables 必须只宣传 HTTPS 端点

重要

strict 仅在 Broker 和 Channel 接收器/入口处强制执行。当 broker 或 channel 将事件发送到订阅者时，如果该订阅者只有一个 HTTP 地址，则 broker 或 channel 仍然可以通过 HTTP 而不是 HTTPS 发送事件。

例如，要启用 strict 传输加密，config-features ConfigMap 将如下所示

apiVersion: v1
kind: ConfigMap
metadata:
  name: config-features
  namespace: knative-eventing
data:
  transport-encryption: "strict"

配置其他 CA 信任捆绑包

默认情况下，事件客户端信任系统根 CA（公共 CA）。

如果您需要为事件添加额外的 CA 捆绑包，可以通过在 knative-eventing 命名空间中创建带有标签 networking.knative.dev/trust-bundle: true 的 ConfigMap 来实现。

重要

每当更新 CA 捆绑包 ConfigMap 时，事件客户端将在建立新连接时自动将它们添加到其受信任的 CA 捆绑包中。

  1. 为事件创建 CA 捆绑包
    kind: ConfigMap
metadata:
  name: my-org-eventing-bundle
  namespace: knative-eventing
  labels:
    networking.knative.dev/trust-bundle: "true"
# All data keys containing valid PEM-encoded CA bundles will be trusted by Eventing clients.
data:
  ca.crt: ...
  ca1.crt: ...
  tls.crt: ...

重要

使用一个不太可能与现有或未来的事件提供的 ConfigMap 名称冲突的名称。

对于分发 CA 信任捆绑包，您可以利用 trust-manager，但这不是必需的。

信任特定事件发送方的 CA

事件源、触发器或订阅被视为事件发送方，并且可以配置它们来信任特定的 CA 证书。

重要

CA 证书必须是 PEM 格式的证书。由于这是一个多行 YAML 字符串，请确保 CACerts 值缩进正确，否则在创建资源时将不会被接受。

触发器和订阅可以配置如下

spec:
  # ...

配置自定义事件源以信任事件 CA

创建自定义事件源的推荐方法是使用 SinkBinding，SinkBinding 将作为投影卷将配置的 CA 信任捆绑包注入到每个容器中，使用目录 /knative-custom-certs。

注意

一些组织可能会将公司特定的 CA 信任捆绑包注入到基础容器镜像中，并自动配置运行时（openjdk、node 等）来信任该 CA 捆绑包。在这种情况下，您可能不需要配置您的客户端。

使用 my-org-eventing-bundle ConfigMap 的前面示例，其中数据键为 ca.crt、ca1.crt 和 tls.crt，您将有一个 /knative-custom-certs 目录，其布局如下

/knative-custom-certs/ca.crt
/knative-custom-certs/ca1.crt
/knative-custom-certs/tls.crt

然后，可以使用这些文件将 CA 信任捆绑包添加到向事件发送事件的 HTTP 客户端。

注意

根据您使用的运行时、编程语言或库，有不同的方法可以使用命令行标志、环境变量或读取文件内容来配置自定义 CA 证书文件。有关更多详细信息，请参阅其文档。

将 SelfSigned ClusterIssuer 添加到 CA 信任捆绑包

如果您正在使用 设置自签名集群颁发者 部分中描述的 SelfSigned ClusterIssuer，您可以通过运行以下命令将 CA 添加到事件 CA 信任捆绑包中

  1. 从 OpenShift cert-manager 操作员命名空间中的 knative-eventing-ca secret 导出 CA，默认情况下是 cert-manager
    $ kubectl get secret -n cert-manager knative-eventing-ca -o=jsonpath='{.data.ca\.crt}' | base64 -d > ca.crt
  2. 在 knative-eventing 命名空间中创建 CA 信任捆绑包
    $ kubectl create configmap -n knative-eventing my-org-selfsigned-ca-bundle --from-file=ca.crt
  3. 使用 networking.knative.dev/trust-bundle: "true" 标签标记 ConfigMap
    $ kubectl label configmap -n knative-eventing my-org-selfsigned-ca-bundle networking.knative.dev/trust-bundle=true

验证功能是否正常工作

将以下YAML保存到名为default-broker-example.yaml的文件中
